2 (c1. lee-122) This invention appertains to new and useful improvements in grain loaders or conveyors, the principal object being to provide a simple and readily portable unit for the eiiicient loadin and unloading of grain from cars, wagons and other vehicles.

The principal object of the present invention is to provide a grain loader which has a wide range of adiustability to meet various awkward conditions that are met in the every day handling of grain loads.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings: 1

Figure 1 represents a side elevational view of one form of the invention.

Figure 2 is an end elevational view of the structure shown in Figure l.

Figure 3 is a fragmentary longitudinal sectional view taken on the line 3-4 of Figure 2.

Figure 4 is a side elevational view of a slightly modifledform of the invention.

Figure 5 is a fragmentary side elevational view of a third form of the invention.

Referring to the drawings wherein like numerals designate like parts, it can be seen in F18- ure 1, that numeral 5 denotes an elongated tube having a screw 8 longitudinally disposed therein,

this tube having an inlet 1 at one end and an outlet 8 at its opposite end. Suitable bearings are provided for the screw 6 and the inner end of the screw 6 has a bevel gear 9 which meshes with a bevel gear ill on a transverse shaft Ii which extends transversely through the tube 5 and is equipped with a pulley at one end over which a belt I! is trained, this belt I 2, in turn, passing over a pulley on a drive shaft I! which forms part of a power plant it.

The power plant I4 is mounted on a. platform I! which is supported by a cradle [8 supported by the shaft II, the cradle it being provided with ears l8 formed with openings through which the shaft II is disposed. Any suitable means may be provided to maintain the cradle it and platform 15 horizontal, such as a suitable prgp arranged between. the cradle and the turn,

is trained, this belt, in turn, passing over a pulley on a shaft Ha which is transversely disposed through the adjacent end of the tube Ia and which, of course, is in driving connection with the screw is. Obviously, this arrangement permits various positionings of the tube Do for accurate loading or unloading of grain and other materials. Y

A third form of the invention is shown in F1!- ure 5 wherein a tube 5b contains a conveyor screw 6b and in this form of the invention clamp rings are provided on the butt end of the tube to for the purpose'of supporting elongated plates 26, these'in turn supporting risers 2'! which, in turn, support a platform 28 on which an electric motor .28 is secured. The screw 6b has a shaft extension 30 extending through the butt end of the tube 5b and this has a pulley or pulleys over which a belt or belts 3| are trained, these, in being disposed 'over corresponding pulleys on the armature shaft 82 of'the motor 28. A suitable stand 33 is provided for this end of the tube 511.

While the foregoing specification sets forth the invention inkspeciflc terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

l. A readily portable grain loading or unloading conveyor unit comprising an elongated tube closed at the ends thereof and having oppositely facing inlet and outlet openings in the body thereof near opposite ends of the same, a con-' veyor screw in the tube, a transverse shaft journaled in one end of the tubeand geared to one It can now be seen, thatwith the power plant H in operation, the tube 5 and the screw shaft I therein can be swung in the manner suggested by broken lines in Figure 1.

A modified form of the invention is shown in Figure 4 wherein a tube Ia has an inlet hopper Ia at one end and an outlet to at its opposite end, the tube In. containing a conveyor screw to.

In this form of the invention, a power plant a may be set apart from the lime:- or lower end of the tube 5a and the same has a drive shaft Ila driving a pulley over which a belt Ho end of the conveyor screw within said tube, a motor supported by said transverse shaft above said one end of the tube, and a'belt gearing between said motor and said transverse shaft permitting said tube andvconveyor screw to move to different angular positions relative to the motor. 4

2. A grain loading or unloading conveyor comprising a tube closed at the ends thereof and having oppositely facing inlet and outlet openings in the body thereof near opposite ends of the same, a cradle disposed over and pivoted toone end of the tube, a motor mounted on the cradle, a drive shaft passing transversely through the tube and operatively geared to one end of the screw,. said shaft constituting the pivot of said cradle, and a belt gearing between the motor and said transverse shaft permitting pivotal movement of the tube and conveyor' screw relative to the motor.
